Boardview in BDV format for the Wistron Ghibli project, board 18803-1, with 0GY02 also given in the name. That extra code is probably a part number but is not explained. Wistron identifies projects by code name and a five-digit board number, and the PCB silkscreen should show 18803-1. The zip is 138 KB and opens in viewers that support BDV, such as OpenBoardView or FlexBV. Use it to locate components and test points alongside the matching schematic.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cynetitsolution. Enginerys does not host this file.
